A Texas Supreme Court representative confirmed a group of ranchers Monday asked the court Monday to review a dispute with the Central Texas Cattlemen’s Association over grazing rights at Fort Hood.

The association allegedly revoked the ranchers’ rights to graze their cattle on land occupied by Fort Hood, passed down from the ranchers’ ancestors, according to Law 360, an online news agency that reports on legal issues.

According to the lawsuit filed in Coryell County’s 52nd District Court, Kenneth L. Haedge, Dale C. Tippit, Denver Tippit, Case S. Jones and Clinton H. Shed filed suit against the association on May 1, 2015, alleging the cattlemen’s board essentially engaged in an unlawful power-grab by removing the ranchers’ access to the post — a right handed down through the family since the agreement was reached with the Army in 1942.

A response waiver was filed in the Texas Supreme Court on Tuesday, but if the court accepts the case, it could be at least five months before a decision is made, said Osler McCarthy, a court spokesman.

According to Law 360, the ranchers argue that the case is unique because the government — not the association — granted the grazing rights to the members and the rights can’t be sold on the open market, only transferred to descendants of the original landowners.
